longer changes between no load and
full load conditions.

• When the limit is reached, the
drive displays , and either the
acceleration time increases or the
output frequency decreases.
• Digital outputs can also indicate
when the limit is reached; see P40,
P42.
• Refer to section 2.2 for CLim

DC Brake
Voltage 0.0 0.0 {%} 0.0 Setting is a percent of the nominal DC
bus voltage.
DC Brake Time 0.0 0.0 {s} 999.9
Note
CONFIRM MOTOR SUITABILITY FOR USE WITH DC BRAKING
DC Brake voltage (P74) is applied for the time specified by P75 with the
following exceptions:
• If P=,  and P75=999.9 the brake voltage will be applied
continuously until a run or fault condition occurs.
• If P0=2, 4… and P75=999.9, brake voltage will be applied for 5s
• If P2…P2=8 and the corresponding TB- input is CLOSED,
brake voltage will be applied until the TB- input is OPENED or a fault
condition occurs.
Display
Frequency
Multiplier 0.00 0.00 50.00 • Allows frequency display to be
scaled
• P78 = 0.00: Scaling disabled
• P78 > 0.00: Display = Actual
Frequency X P78
Example: If P78 = 29.7 and actual frequency = 0 Hz,
Drive displays 750 (rpm)
Run Screen
Display 0 0 {Parameter Number} 599 • 0 = Normal Run Screen, this display
depends on mode of operation.
See Section 4.2.
• Other selections choose a diagnostic
parameter to display (P50…P599).
Skip frequency  0.0 0.0 {Hz} 500 • Drive will not run in the defined skip
range; used to skip over frequencies
that cause mechanical vibration
• P8 and P82 define the start of
the skip ranges
• P84 > 0 defines the bandwidth of
both ranges.
Skip frequency 2 0.0 0.0 {Hz} 500
Skip frequency
bandwidth 0.0 0.0 {Hz} 0.0
Note
Bandwidth (Hz) = f
s
(Hz) + P84 (Hz) f
s
= P8 or P82
Example: P8 = 8 Hz and P84 = 4 Hz; skip range is from 8 to 22 Hz
() Any changes to this parameter will not take effect until the drive is stopped
